"The decision to adopt train sets technology was announced in the 2012-13 Railway Budget. We are planning to introduce it on Delhi-Chandigarh and Delhi-Amritsar routes and a decision to this effect is likely to be taken soon," he said.

AC double decker with improved passenger-friendly design and capacity of 120 passengers per coach will run at 110 km per hour speed, he said.

"The Rail Coach Factory (RCF) at Kapurthala has been asked to expedite manufacturing of double decker coaches to meet the February target, and Northern Railway is working out the time schedule for introducing the AC double decker train

service between Delhi and Chandigarh," he said.

Indigenously designed, developed and manufactured at RCF Kapurthala, the air-conditioned double decker train was introduced for the first time between Howrah and Dhanbad followed by Delhi-Jaipur and Ahmedabad-Mumbai routes.

There will be two more AC double decker trains for Habibganj-Indore and Chennai-Bangalore routes in the near future, the official said.

Railways has decided to equip all new double decker coaches with automatic smoke detector systems to prevent fire incidents.
